Solid wood door industry "material trap" can not be prevented

Nowadays, many consumers like solid wood doors, but consumers are hard to distinguish the quality of materials. This makes some solid wood door brands use materials to make a fuss, which leads to the phenomenon of shoddy, cheap and expensive. It is impossible to prevent.

Interpretation of the advantages and disadvantages of solid wood doors

The advantages of solid wood doors, after the solid wood panels are painted, the surface has no unevenness of rubber joints and slats, and the physical properties are relatively stable during long-term use; the wood utilization rate is high, in line with the principle of raw material ecological utilization. Therefore, in terms of use and texture color, the solid wood panel decoration board is more suitable for the use of furniture and decorative functions; although the amount of glue applied to the solid wood panel is larger than that of the solid wood panel, it is protected by double-sided thick veneer and four sides. The thick veneer edge is actually only 8 seams on both sides and 4 sides. Therefore, the chemical substances volatilized by the adhesive in the solid wood panel are far lower than the volatilization of the solid wood panel and solid wood composite material, which is more environmentally friendly and healthier. . Since the core plate is made of an anisotropic small wood, the surface of the plate is uneven and the degree of warpage is small, and the upper and lower sides are covered with two thin wooden veneers, which can better eliminate the unevenness and cracking of the plate surface. And can improve the physical strength of the board in all directions; sliced ​​thin wood veneer is a selection of excellent logs of large diameter grade, and according to the strict selection of texture and color, using high-precision equipment and scientific cutting method. This kind of processing technology is very good in texture and color, and it has more outstanding texture after painting. The production of positive furniture can create a sense of harmony and high-grade value.

The main disadvantage of solid wood doors is that they are easily deformed and difficult to maintain. For example, you can't let the sun shine directly, you can't overheat and overheat, too dry and humid environment is not suitable for solid wood doors; if you don't pay attention when using it, frequent switching air conditioners cause excessive temperature and humidity changes, even qualified solid wood door products sometimes Deformation and cracking can also occur. It can be said that no matter what kind of wood is used and how to work, it is difficult to avoid these problems.

Identify real solid wood doors

The price of solid wood doors is very high. How do you identify real solid wood doors in the current development of counterfeiting technology and various products?

A look: real solid wood varieties rarely have large areas of beautiful texture. Second smell: Pure wood has its own special taste, even after long-term storage or finishing, there is still a smell, such as pine has the taste of turpentine, cedar has a light fragrance, cedar has a spicy taste, and eucalyptus has a very obvious camphor taste, and Artificial boards have a strong chemical smell, such as formaldehyde. Three knocks: The soft wooden pieces will give a crisper sound when tapped by hand, while the artificial boards will have a low sound, and the wooden pieces of the box will make a loud drum sound. Four plaques: Many solid wood doors are lighter than particleboard and medium density fiberboard doors.

How to correctly identify solid wood. The first type is most common, that is, a layer of solid wood skin is applied to the surface of the wooden door, which is similar to the solid wood door from the surface. Consumers need to be careful to observe, it can be easily identified. The second type is the finger joint plate which is made of solid wood small pieces which are processed by deep processing as the base material of pure solid wood door, and then the outer solid wood skin.

When consumers buy solid wood doors, they must know which wood they are all-wood doors. Although it is a hardwood pretending to be a solid wood door, fortunately it is still natural wood, but it has been deceived at a certain price. Some use artificial synthetic wood instead of natural wood, and the harmful substances exceed the standard, not only deceiving consumers in price, but also seriously endangering people's health.
